The invention discloses a horizontal 
drying device for 
lithium battery 
raw material particles. The horizontal 
drying device comprises a box body, a charging 
barrel, a feeding funnel, a discharging funnel, a fan and a heating 
resistance wire, wherein arc-shaped plates are symmetrically arranged in the box body, the arc-shaped plates are fixedly connected to the bottom of the box body through supporting plates, annular plates are rotationally connected to the arc-shaped plates, and the two ends of the charging 
barrel are fixedly connected to the opposite side walls of the two annular plates correspondingly, the feeding hopper is fixedly connected to the top of the box body, and the lower end part of the feeding hopper communicates with the charging 
barrel, the discharging hopper is located at the end, away from the feeding hopper, of the charging barrel and fixedly connected to the bottom of the box body, and the lower end of the discharging hopper penetrates through the bottom of the box body and extends to the lower side of the box body. According to the horizontal 
drying device, the drying speed of 
lithium battery 
raw material particles can be increased, the production cost of 
lithium batteries is reduced to a certain extent, meanwhile, the 
lithium battery particles can be conveniently loaded and taken out, and convenience is brought to workers.
